Error E22 on Siemens dishwasher

The Siemens dishwasher error code E22 might be familiar to you. This code can be annoying, particularly if it shows up right when you need your dishwasher to function. Nevertheless, what does it actually mean, and how can it be fixed?

Error E22 usually denotes a filter system issue with the dishwasher. It is an indication that the filter is obstructed or clogged, which is preventing the water from draining correctly. The good news is that there are usually a few easy steps you can take to resolve this issue.

This post will explain the causes of the E22 error, how to clean the filter, and what to do if it keeps happening. You can easily get your Siemens dishwasher back in working order by following these instructions.

A Siemens dishwasher that displays error E22 usually has a drainage issue with water, which is frequently the result of a blocked drain pump or clogged filter. You can try cleaning the filter and looking for any obstructions in the pump to fix this problem. To make sure your dishwasher functions properly once more, professional repair might be necessary if the issue continues.

Common reasons why water does not drain

Let’s first identify every potential cause of draining issues in Siemens dishwashers. These are the most common, fundamental issues that are also the simplest to resolve.

• The drain hose is pinched. This could happen because the drain hose is bent somewhere, or a heavy object was accidentally placed on it, for example, the dishwasher itself, which blocked the flow of water. In this case, resetting the E22 error is very simple – you just need to straighten the hose, remove unnecessary objects or equipment from it, and then check for damage. Be sure to check the functionality of the Siemens machine after the manipulations. This will help you understand whether the error code has disappeared or not.
• Clutter filter. This usually happens due to foreign objects, such as food debris, meat and fruit bones, napkins, tea bags, and glass fragments. It is also easy to fix the situation – you need to clean the filter, and do not forget to clean it at least once a month for preventive purposes.

In order to prevent foreign objects from clogging the filter element, the manufacturer advises against loading dirty dishes into the washing chamber that have food debris on them.

• The pump or drain pipe is clogged. And in these elements, foreign objects can cause the E22 error, since the debris will clog the parts and prevent the waste liquid from going into the sewer after the working cycle.

The E22 error most frequently appears in Siemens dishwashers under these three circumstances. In the sections that follow, we will examine the solutions in greater detail.

You haven"t cleaned the filter for a long time

If the cause is a clogged drain filter, you can resolve the issue in 30 minutes or less on your own. You require routine cleaning in this case, and it should be done at least once a month. How should I handle this?

• First of all, drain all the waste liquid that remains at the bottom of the washing chamber after washing. The easiest way is to put a large container under it, disconnect the drain hose and activate the drain manually. This will also help to assess the pipe and sewer for blockages.
• After draining all the water, you can proceed to cleaning the filter element. First, disconnect the Siemens dishwasher from all communications and remove all the baskets for dishes from the hopper. Then remove the trash filter from the bottom of the washing chamber, and then the mesh installed below it. Remove all dirt with a brush and a powerful stream of hot water from the tap.

You can soak the parts in a citric acid solution for at least an hour if the parts are resistant to dirt.

You must inspect the sink by running an idle cycle without dishes after reassembling. You should look into other possibilities if the error code E22 is still visible on the screen.

The pump is out of order or blocked

In the event that the filter element is clean and in good working order but the water still does not enter the sewer, you should examine the pump’s impeller for potential blockages caused by broken dish shards. You will need to disassemble the equipment in order to reach this unit. You can disassemble the Siemens "home assistant" yourself if the warranty has long since expired.

• We have already drained the water, but you still need to tilt the dishwasher on its side a little to get rid of the remaining water.
• Use a sponge or cloth over the garbage filter to remove all the moisture.
• Put the machine on its back wall.
• Disconnect the clamps holding the bottom of the device.
• Carefully disconnect the Aquastop sensor installed on the other side of the tray.
• Disconnect the wires connected to the pump, unscrew the clamps and remove the element itself.

To aid in reassembly, snap a few pictures showing the wires connected correctly.

The pump cover must be removed in order to thoroughly check the impeller for foreign objects. If there was glass within that actually prevented the part from moving, it needed to be carefully removed, and the impeller’s rotation needed to be verified. After that, you should connect the device probes to the pump contacts, switch the multimeter to the resistance measurement mode, and review the data. The resistance should normally be around 200 Ohms, but if the tester displays significantly different values, a new pump needs to be installed.

A clogged filter is typically the cause of the E22 error that appears on your Siemens dishwasher. You can avoid this problem and maintain the smooth operation of your dishwasher by routinely cleaning the filter.

Maintaining your dishwasher for a few minutes now can prevent more serious issues later on. Maintaining a close check on any error codes that appear and taking quick action to fix them can help your appliance last longer.

After cleaning the filter, if the E22 error still occurs, it may be necessary to have a professional inspect the system more closely. Early intervention can help avoid more extensive damage and expensive repairs.
